Switching to the new tax regime - what actually changes for you
The new regime is now the default, but default is not the same as best. Niyam runs both regimes on your real salary structure, shows the difference in rupees, and tells you the exact deduction level at which the old regime would win instead.

Who it is for
- Salaried employees deciding which regime to declare to payroll this year
- Anyone whose 80C, HRA and home-loan mix has changed since last April
- People who picked a regime once and never re-checked it
What Niyam does
Runs both regimes on your numbers
Not a generic calculator. Niyam uses your CTC break-up, HRA and declared investments to compute tax under both regimes, down to the rupee.
Finds your break-even
It calculates the deduction total at which the old regime overtakes the new one, so you know how much you would need to invest to justify switching back.
Turns the verdict into steps
One declaration to file with payroll, plus what to do with the tax-saver investments you were holding only for the deduction.
